The Runaways wake up to find people who look to be from the 20s throwing a party in the hostel.
They run into a magician named Quinton le Fay, the original owner of the hostel, who is putting on a show.
They realize their powers don't work.
Quinton saw Victor, Stacey, Tina, and Alex in the hostel as well. The Runaways believe that they were separated from the aliens when Nico blasted them.

Nico and Amy go to their house the day Amy died.

Nico shows her mother that nothing is real. Tina realizes they are in the dark dimension.
Gert wakes up and realizes that Stacey had mindwiped her in the memory when she was thirteen. She believes this is what caused her anxiety.
Destiny tells Karolina that the darkness comes every night and feeds on one of them. They tie Karolina up and use her as a sacrifice.

Amy comes back and tells them she's an emissary of Morgan le Fay.
She made a promise to hand over Nico to Morgan but can't now that she's seen all of their bonds and is reminded of her past life.
